Magnetic levitation promotes the disadvantage of traditional air-conditioning is difficult to shake

"Sadie Network News" May 28, since the Ministry of National Housing soon announced the "Twelve-Five Green buildings and green eco-urban Development planning", the public building to determine the main areas of energy saving, the appeal of traditional central air-conditioning replacement voice. Although many voices believe that China's central air-conditioning will usher in a broad alternative market, but because of the high cost of energy-saving central air-conditioning products business options, less energy-saving products led to low consumption of central air-conditioning market share low and central air-conditioning users of the poor sense of energy conservation and other factors, the traditional central air-conditioning alternative to the Objectively speaking, the substitution of high energy consumption central air-conditioning is imperative, but China's traditional central air-conditioning in the short term difficult to be shaken. Traditional central air-conditioning significant economic advantages of the alternative market data show that as of 2011, China's public building area of about 2 billion square meters, if all replace the use of magnetic levitation energy-saving central air-conditioning, in accordance with the cost of 120 yuan per square meter, this alternative market cake will be up to 200 billion yuan. But this tempting 200 billion-dollar cake is not easy to slice. To energy-efficient magnetic levitation energy-saving central air-conditioning, for example, its cost per square meter of 120 yuan compared to the traditional central air-conditioning 70-80 yuan square meters of the cost of nearly one-third of the difference. Other types of energy-saving central air-conditioning installation costs are higher than the traditional central air-conditioning. In addition, as China's central air-conditioning use rate is low, the current central air-conditioning enterprises have high energy consumption products inventory. In the global energy-saving environment and national energy conservation policy urging pressure, central air-conditioning manufacturers have to use promotional means to play a "price war" sales of traditional central air-conditioning. has been close to the cost of high energy consumption central air-conditioning to occupy the original price advantage of the central air-conditioning market, so that it is in a passive position. In the developer to reduce all building production costs on the basis of high energy consumption central air-conditioning due to a significant price advantage, 200 billion traditional central air-conditioning replacement market cake had to share a cup of soup. Energy-saving central air-conditioning category single impact on the market share another point of view, under the support of national policy, the traditional central air-conditioning will no longer have the price advantage. But analysis of the prevalence of energy-saving central air-conditioning, the total area of China's existing building has more than 43 billion square meters, and the use of energy-efficient central air-conditioning building less than 1%. The reason is that to meet the green energy-saving requirements of energy-saving central air-conditioning category is one of the important factors. Although the current market, such as LG Multiv series inverter More online, the United States super efficient two-stage compression film-type centrifugal unit, Haier magnetic levitation energy-saving central air-conditioning, gree DC inverter Centrifuge Central air-conditioning are played energy-saving or even energy saving 50% of the slogan, but because the main equipment is the air conditioner pump, By changing the number of compressor units, pumps and fans to save energy and reduce consumption, the effect of energy-saving central air-conditioning is still to be verified. In this respect, Xu WENFA, director of the National Regional Energy Professional Committee, said, "If the best energy-saving emission reduction effect, only a single device, with a system, with a technologySurgery is not fully realized. Energy-saving emission reduction came to 21st century, the requirements for a variety of equipment, systems, technology to carry out comprehensive, integrated, complementary to each other to achieve the best results. "Up to now, the domestic central air-conditioning industry has only a Haier enterprise first put forward quite nearly as much as 200 billion yuan energy-saving alternative market, but to rely on magnetic levitation central air-conditioning to win such a huge market cake, obviously there is a long way to go." In addition, because the state does not pay attention to the central air-conditioning energy-saving impact on building energy consumption and led to a weak sense of energy-saving central air-conditioning system in the entire construction costs accounted for a small part. Only more than 10 years of use of central air-conditioning compared to the construction of "longevity", because of its high replacement frequency, businesses do not think that investment energy-saving air-conditioning can bring consumption savings, and thus neglected the upfront investment problem. Therefore, although the traditional central air-conditioning replacement is imperative, short-term central air-conditioning mainstream status is still difficult to be shaken.
